After following the recent long and somewhat contentious thread on heat-related risks on Skyline, I decided to comb through RMRU's public descriptions of summertime deaths and rescue missions on Skyline and take some notes. This is in reverse chronological order. I'm sure it isn't a comprehensive list. It's mostly just what I found on RMRU's site.

2008 Sep 4, survived
Hiker didn't turn left in front of Coffman's Crag, ended up stuck in Chino Cyn. Called 911 on her cell phone, and eventually they talked her out and she exited by herself.

Sean Stewart, 2000 July 1, age 32, survived.
High of 106 in PS. Started up Skyline at 10 am. Turned down Tahquitz Cyn for water. Made a signal fire, which went out of control. Rescued by helicopter.

Mike Blotter, 1976 Aug 16, survived.
High of 93 in PS. Carrying two army canteens, intending to stay out overnight. Ran out of water at 3800'. Walked out Tahquitz Canyon while RMRU was searching for him on Skyline.

A common denominator is that a lot of these people seem to have started much too late in the day (in addition to the risk factor of attempting Skyline in the summer at all).

I hadn't known how common it was for people in trouble to end up in Tahquitz Canyon, either because they get lost or because they intentionally decide to retreat that way rather than coming back down Skyline. It would be good to get comments from people who know about Tahquitz Canyon about whether this is a reasonable last-ditch survival strategy. Apparently there is water there, and I suppose it might have some shade, so if you're in danger of dying of heat stroke, maybe it makes sense to go there...? But it violates the rule of staying put when you're in trouble so that people can find you, and it also sounds like the majority of these people are unable to get out of Tahquitz Canyon under their own power, and have to be helicoptered out.

A lot of people got lost. Clearly anybody who's not pretty familiar with the trail should not be attempting it alone. I'm sure a lot of people doing it for the first time don't understand that it's really a cross-country route with a use trail along parts of it. They probably hear "Skyline Trail" and imagine a maintained trail.

Here's the 5/15 rescue, highlights the danger of hiking down. These two planned to come down, but I'm posting it to emphasize Cynthia's point that it's a committed hike UP when temps are high.

Palm Springs police rescued a hiker after he became overwhelmed by the heat and couldn't walk anymore, police said Monday.

The hiker, identified as Jim Lieser, and his friend started their hike down the Skyline Trail from the Palm Springs Aerial Tramway about 9 a.m. Sunday.

Lieser called his family about 4:30 p.m. and said he was “distressed from the heat and unable to walk any farther,” Sgt. Marc Melanson said. He was at about 2,500 feet.The family called 911, and the Palm Springs Mounted Police Search and Rescue Unit was sent to rescue him, with help from the California Highway Patrol.

The volunteer rescuers airlifted Lieser to a landing zone on the ground level in Palm Springs, treated him for dehydration and took him to a nearby hospital.

Police issued a reminder Monday for hikers to be cautious as the temperature continues to climb.

Thanks for the information. Of course, this is only part of the story on Skyline. Any self rescues, rescues by other hikers, rescues by Palm Springs Mounted Posse (not actually on horseback up Skyline), rescues by the State Park, rescues by the County Sheriff's helicopter without RMRU asistance and others that I have forgotten to mention, do not show on the RMRU website.

As far as Tahquitz Canyon (and Long Valley Creek canyon- that's where John Donovan died) can be very dangerous. Lots of "dry" waterfalls (steep cliffs) and terrible vegetation. Not a good idea to go down it.

Howdy Florian. Yeah I know Mike and Tom too. All I can say is that those Blotter's are a wild bunch. Bcrowell, the canyon can be walked/scrambled from Ramon/Mesquite all the way up to where Tahquitz creek splits, with one branch going up to Long Valley, and the other heading up to Carumba Camp. From that point it gets really steep. The creeks go up huge waterfall rock that require good climbing skills. If you don't have them, you'll wish you had a rope. The canyon walls around the creeks are covered with a Tarzan like jungle of mesquite, that you either crawl under, over or through. If you were dying of thirst on the Skyline in 105 degree heat, Tahquitz could look like Shangra-La to you, but if you hit wrong, you could be in a world of hurt, if not the entry portal to your next incarnation.

Reminded of some old sayings from friends who have passed
on into the big campsite in the sky;
"Mother Nature doesn't forgive one's mistake."
"Don't make your poor planning; my crisis."
and the classic
"You play, you pay." Don't get me wrong. I am saddened to hear of another lose of
life no matter what the environment or low cal (local) is. Just saying,
Come on people, getting to the TOP is only half way. You still have
to come down.
Be safe/Be Prepared
See ya at the top!

From what I can tell, almost all of these rescues or deaths were caused by simple mistakes (starting too late, trying to hike down, getting lost) that could have been avoided if they had been better informed.

If we really want to cut back on unnecessary casualties, I think a better approach might be to create an informational flyer about hiking Skyline (risks, preparation, contingencies) and post it at the trailheads.
